Research on interactive visual simulation method of Chinese fir stand growth and cutting process

Based on the current status of forest visual simulation and tree growth-oriented management theory, and referring to fir stand growth and management process interact, the paper analysed the stand management process and growth interact process, combining with stand growth modal, the paper designed a visual simulation approach of management and stand growth interact feedback. By using the stand growth result and stand management measurement as interface parameter, analysing process defined management plan, by real-time scheduling algorithm parsing the management process , and by using management processes and stand growth dynamic visualization to get the final result of stimulation management result. Sub-fir growth and management process simulation for interactive visualization can provide a scientific basis for management planning and decision-making.
